Abstract
The invention relates to a sensor, which is a device capable of detecting the changing inductance of a coil. The ground induction coil sensor adopts the technical essential that a display part is used, so that man-computer conversation can be realized, the sensitivity parameter is set by changing the program parameter, and the working frequency is automatically searched and adjusted to the suitable frequency band. When in detection, a working circuit has no mechanical contacts caused by a set switch, no oxidation or poor contact phenomenon, so that the detector works stably. The ground induction coil sensor is suitable for working in the humid and dusty environment and is used for the road vehicle detection, the traffic signal control and the vehicle management in parking lots.
Description
Technical field
This patent relates to a kind of sensor, the device that energy magnetic test coil inductance value changes.Especially the ground induction coil sensor in road vehicle detection, traffic signals control, the parking lot.
Background technology
At present, known ground induction coil sensor is set the sensitivity parameter of induced signal by the Switch device of operating machine (toggle switch, rotary switch), knows the parameter of sensitivity from the station location marker of mechanical switch, and unmanned-machine dialogue function.Be exposed to airborne configuration switch contact point surface through moisture, dust, these reasons of air oxidation, cause the operating circuit loose contact, make the sensitivity instability.Await improving.
Summary of the invention
For making the ground induction coil sensor long-term work stable, this device takes to be with display unit, can person-machine dialogue, set the parameter of sensitivity by the change of program parameter, and the suitable frequency section is searched for and be adjusted to frequency of operation automatically.Because the Mechanical Contact point that does not exist configuration switch to cause in the operating circuit loop when detecting, sensors work is stable.Be suitable for the work down of humidity, dust environment.
The beneficial effect of this patent is stable ground induction coil pick-up unit to be provided for the road vehicle detection system, traffic signal control system, the parking lot that are in work under humidity, the dust environment.
Description of drawings
Accompanying drawing is the block diagram illustrations of this device, wherein:
Microprocessor---be the core of this device, each several part work is coordinated in control.
Set---concrete desired parameters is sent into microprocessor.
Show---the parameter in the reflection program, realize person-machine dialogue.
Excitation---provide bigger working current to oscillator coil.
Vibration---constitute by LC, produce magnetic field, when winding inductance quantity changes, the information that changes is passed to microprocessor.
Temperature---ambient temperature information is provided, makes this device-adaptive temperature variation.
Output---set according to sensitivity, testing result is provided.
Embodiment
Be embedded in underground coil and be connected on " vibration " interface section,, carry out person-machine dialogue, finish parameter setting, promptly be operated in suitable frequency band after the system restart, set, testing result is provided according to sensitivity by " setting " on the panel and " demonstration ".
Claims (2)
